SM/PM 光纖耦合SLD模塊(770-890nm中等功率光纖耦合SLD模塊)
我們的主要產(chǎn)品是波長從650nm到1620nm具有不同譜帶的單模尾纖SLD模塊。
我們正在為不同的應(yīng)用制造制冷(有制冷器和電熱調(diào)節(jié)器)和非制冷的模塊，像光纖陀螺儀、OCT、光纖組件測(cè)試、光計(jì)量學(xué)和大量的其它模塊。我們也提供自由空間模塊，特別是用于原子力顯微術(shù)，但也包括無斑紋照明、白光干涉測(cè)量、光學(xué)試驗(yàn)和測(cè)量以及其它模塊。

* Maximum output power is guaranteed at a forward current of 160 mA or less.
** 830-nm wavelength is not guaranteed if it is not mentioned in the order. See
part numbers below.
*** Residual spectral modulation depth and secondary coherence subpeaks are
specified at an output power of 1.5 mW ex fiber.
**** Case temperature (depends on package style). The specification shown is
the case temperature for butterfly-packaged modules.
Additional and customized:
- wider spectrum, higher power, lower spectral ripple for meeting
customer requirements—see the next page for performance examples;
- FC/APC terminated pigtails;
- PM fiber coupled, polarized or pseudo-depolarized (light is launched into
the fiber at 45 degrees to the birefringent axes) versions.
The following part numbers should be used for ordering:
SLD-381-MP-(c)-(d)-PD-XXX,
where:
c – package type, DIL14, DBUT(butterfly) or SBUT (semi-butterfly),
d – type of fiber, SM (isotropic) or PM (polarization maintaining),
XXX – wavelength (in nanometers).
Example: SLD-381-MP-DIL-SM-PD-830.
Attention: center wavelength is guaranteed with a tolerance of maximum ±10 nm. If
a closer tolerance is required, contact our company before placing the order. If the
center wavelength is not explicitly specified in the order, an SLD centered at any
wavelength within the range of 830±20 nm may be shipped.
